VII. MITIGATION WORK PLAN CORALS Prior to the start of the relocation project the footprint of the docks and the predicted impact zone will be marked on the seafloor using small pin flags. Any coral or boulder which partially extends into this zone will be relocated. Individual corals that are attached to the near shore hardbottom will be removed with chisels. These corals will be collected in bins and carried to recipient site. These corals will be fixed in placed in their new locations with two-part underwater epoxy, which sets in a matter of minutes (Splashzone). The base of the coral will be carefully cleaned with a wire brush and the new substrate will be cleaned to remove algae and any other material which might interfere with the adhesion of the epoxy or cement. The coral will be carefully placed and held until the epoxy starts to set. Divers will then collect those corals and sessile invertebrates that colonize cobbles and rocks within the dock footprint that are of a small enough size to allow hand carrying. These are cobbles and boulders that are in a range of I ft2 to 2.5ft2. These corals are usually growing on pieces of coral rubble. Divers will wear disposable gloves while working with corals minimize touching live tissue and keep any coral that appear unhealthy or diseased away from other corals. Corals which appear to be diseased will be marked, and not transplanted to the recipient area to minimize the potential of the spread of disease to the recipient site. The diseased corals will be photographed and will be addressed in the baseline report for the transplant identifying the size and location of each individual colony. If a coral is handled that appears unhealthy or diseased gloves will be changed prior to working with other corals. The I ft2 to 1.5112 corals will be placed in underwater bins and carried by divers to the recipient sites. The larger corals will be placed directly on a transport tray. Once the tray is full it will be lifted by lift bags and walked to the relocation site. Once on site the tray will be lowered near the seafloor and divers will remove the corals from the tray. The coral will be placed in the recipient site in such a fashion that the rock is stable and will not be subject to movement. This will be done by digging a depression in the sand to rebury the base to the same depth as it was prior to transplant. Care will be taken to make sure no live tissue is buried or too close to the sand that it may become buried. If possible if hard substrate or other larger rocks or rubble is found the coral base will be attached to it with "Splashzone" two-part underwater epoxy. Care will be taken so that these transplanted materials will not impact existing organisms at the transplant site. Splashzone epoxy is used because it is approved for drinking water systems by EPA. This epoxy does not leach any harmful chemicals into the water. This epoxy also does not create the temperature change which occurs with hydraulic cement. For corals and larger coral colonized rocks, those greater than 2.5ft2, lift bags, and ropes will be utilized. divers will lift and transport larger corals, and coral colonized rocks then slowly carry the organisms to the transport tray. Again when the tray is full it will be EFTA00802826
lifted and walked to the recipient site. When attaching the corals to the lift bags ropes will be placed so that they avoid live coral tissue. If necessary, a plate may be placed underneath corals so that it lifted without the tissue being impacted by the ropes. The coral boulders and larger rocks will be placed in the recipient site in such a fashion that the rock is stable which may require some excavation into the sand to create a depression for the previously buried part of the rock. Care will be taken so that these transplanted materials will not impact existing organisms at the recipient site. Care will be taken to place corals in the same orientation and depth as they were in their original locations. COMPENSATORY MITIGATION To mitigate for impacts that cannot be avoided a special reef building system will be placed beneath the southeastern dock. This system serves not only as a wave attenuator by provides additional substrate to allow for colonization beneath the dock. Grated decking will be used on the dock to facilitate light transmission. .... .2 0 0. .. ID • • % (i),(;) • • 1•`); II < • )0 • • • ...a ....,• • , Ilt•MB 4 • v za .,•• • • •I • >0 A% I • se•Ni.

VIII. MAINTENACE PLAN Divers will survey the recipient site on a bi-weekly basis for the first 2 months after the transplant to ensure that the corals have not become unattached or shifted. If for any reason the corals become loose or move they will be re-situated and or reattached. After the first two months the corals will be monitored on a monthly basis for the first year and then on a bi-monthly basis for the following 2 years then every 6 months for year 4 and 5 after the transplant. During each monitoring event divers will make sure that the rocks have remained stable and not shifted, and that corals and sponges have not come loose. If necessary corals will be repositioned and re-attached. IX. ECOLOGICAL PEFORMANCE STANDARDS The object of this mitigation is to minimize impact to benthic resources which provide high quality habitat to marine species. In order to objectively evaluate the mitigation project, ecological performance standards must be established. The performance standards will include viability of the transplanted corals and sponges and relocated seagrass. It is the intent of this transplanting program to obtain a minimum of 80% survival of the transplanted corals and sponges. Great St. Jim, LLC is committed to put forth the greatest effort to see that the relocation is successful and that they obtain the greatest potential survival of transplanted organisms. X. MONITORING REQUIREMENTS Monitoring the compensatory mitigation project site is necessary to determine if the project is meeting its performance standards, and to determine if adaptive measures are necessary to ensure that the project does meet its objectives. As per the guidelines set forth in §230.96 Monitoring the mitigation project will be monitored for a minimum period of 5 years. In total twenty-five transplanted corals at each site will be marked with numbered tags for monitoring. The tags will be maintained throughout the 5 year monitoring period. The corals will be surveyed for percent live tissue, color, algal growth and indicators of disease and photographed on a monthly basis for the first twelve (12) months. Corals will then be monitored on a bi-monthly basis for the follow 2 years and then every 6 months for years 4 and 5 after the transplant. The percent live tissue, color, stress, surround algal growth, algal growth on dead areas of tissue and any signs of disease for each monitored coral will be noted in the reports. If at any time during the monitoring degradation of the corals is noted, degradation being defined as tissue loss, indication of disease, color change, excessive algal growth or notable mucus, affected corals will be compared to those within the other monitoring quadrats and corals in areas outside the impact area of the project. This information will be used to determine whether the degradation of the corals is due to the transplant, EFTA00802828
activities related to construction or resort or due to natural phenomena (such as wide spread bleaching). If the corals appear to be stress due to the transplant, the reason for the demise will be assessed, poor positioning, sand scour, light attenuation, etc. If necessary, the coral or sponge will be repositioned. Every effort will be made to save the coral or sponge. If the degradation is seen both in the project area non-transplanted corals and the transplanted corals, the reason will be assessed for the demise. If the source of the impact cannot be readily assessed by the monitoring being undertaken, the monitor will work with NMFS and VI Fish and Wildlife and the other resource agencies to expand the monitoring so that the source of the impact can be identified. In order to monitor the success of the reef creating system under the southeastern dock, it will be monitored concurrently with the corals and a detailed photographic recorded will be kept depicting colonization, survival and growth of coral and sponge species. The monitoring results will be delivered to the agencies within two weeks of the monitoring period. If negative impacts are noted the agency will be notified by phone and by email within 24 hours. The agencies will be apprised of what steps are being taken to identify the impact and rectify the problem. The agencies will be provided a detailed report on the steps that are taken and the results of those actions. XI. LONG TERM MANAGEMENT PLAN Great St. Jim, LLC is committed to the survival of the transplanted coral species and the success of the reef building system and will make every effort to ensure that both are a success. XII. ADAPTIVE MANAGEMENT PLAN In the event that there are difficulties with the mitigation or if the mitigation is deemed unsuccessful as planned, Great St. Jim, LLC is prepared to take additional steps to see that compensatory mitigation goal is achieved. If necessary, extended monitoring and maintenance or additional marking of the sites will be undertaken in order to meet the mitigation goal. If the mitigation goal of 80% survival at the end of five years is not met, the applicant will prepare a detailed report of why the mitigation was not successful. Great St. Jim, LLC will meet with the permitting agencies to determine the additional compensatory mitigation needed to meet the mitigation goal. XIII. FINANCIAL ASSURANCES Great St. Jim, LLC will secure a performance bond in the amount of the cost mitigation program and subsequent monitoring throughout the implementation and monitoring period or provide another form of acceptable financial assurance. The bond will follow the guidelines set out by the U.S. Army Corps of Engineers Regulatory Guidance Letter EFTA00802829

APPENCIX C ENVIRONMENTAL AND WATER QUALITY MONITORING PLAN FOR THE CONSTRUCTION OF A TEMPORARY BARGE LANDING AND TWO DOCKS ON GREAT ST. JAMES, U.S. VIRGIN ISLANDS INTRODUCTION The following is the proposed monitoring program for the construction of a temporary barge ramp and two docks on the island of Little St. James. The purpose of this monitoring plan is to evaluate and minimize the impact of the proposed construction on marine water quality and the benthic community. Great St. Jim, LLC is seeking to construct two docks, one of which is a combination dock/ barge landing, and a temporary barge landing to provide access to Great St. James Island. The marine construction will consist of the vibra-hamming or socketingof piles and the placement of docks. The impact pile driving or vibra-hammer driving will have a minimal potential for creating turbidity. However, where rock encountered it is possible that piles may need to be socketed. Pile socketing greatly increases the potential for turbidity, and creates large volumes of rock flour. Based on observations in the field a number of piles may require socketing. Turbidity barriers (silt curtains) will be installed surrounding all pile driving/socketing activities. The curtains will serve not only to maintain turbidity created by pile driving but will also contain floating debris within the project area. The turbidity barriers will be properly installed and will extend to within 1 ft. of the seafloor where piles are driven. If piles require socketing, curtains will extend to the seafloor and a double set will be deployed. ESTABLISHMENT OF BASELINE CONDITIONS AND SAMPLING POINTS Prior to the start of any construction activities a baseline of existing conditions will be assessed. Baseline samples will be conducted over a two-month period. The sampling locations have been established to encompass the area most likely to be potentially impacted during construction. The baseline samples sites are shown in Figures 1 and 2. No monitoring should be necessary for the temporary barge landing. Baseline samples will be tested for secchi depth and turbidity expressed as NTU. As part of the baseline sampling, sampling during normal and storm conditions will be completed prior to project construction to determine the natural range in turbidity and duration of elevated turbidity levels to which corals in the area are naturally exposed. Samples will also be taken after large rainfall events which result in an influx of runoff to determine the existing sediment runoff. EFTA00802831
DURING CONSTRUCTION MARINE WATER QUALITY MONITORING During the construction of the docks water quality at the stations in the vicinity of the work will be sampled on a daily basis. Three water samples will be taken 10 meters outside the turbidity barriers surrounding the area of work. Two control samples shown in Figures 1 and 2 will also be sampled. Water quality will be secchi depth and turbidity expressed as NTUs. ACTION TRIGGERS During construction if the water samples show NTUs, or secchi disk readings outside the allowable regulatory limits, the reviewing agencies and the applicant will be notified, in writing within 24 hours of the parameter exceedance. The baseline samples will be utilized to determine if other parameters are elevated above normal background levels. Controls will also be used to determine if the readings are a result of natural phenomena or if the monitoring sample is elevated above the ambient background as a result of the construction project. If it is determined that the elevated turbidity is the result of the construction project, the source of the elevated turbidity will be identified and methods worked out to abate the degradation. Someone will be on hand at the construction site at all times who has the authority to implement sediment control devices or other remedial actions, so that problems can be resolved as quickly as possible. Once the source of the impact is identified, steps will be taken immediately to abate that impact. The action that was taken to resolve the issue, as well as confirmatory sampling data that the degradation has been resolved will be included within the written report to the agencies and GSJ. A monitor will be on site throughout the day during construction activities to ensure that turbidity barriers are adequate maintain and that escaping sediments do not go unabated. REPORTING OF DATA In the event of any emergency or noted degradation in any of the water quality parameters above the allowable or acceptable limits, or any impact to the benthic community the owner and the reviewing agencies will be immediately notified in writing by e-mail. NMFS will be notified immediately of any impact to ESA listed species. Weekly water quality reports will be delivered to all agencies and GSJ throughout the monitoring period. EFTA00802832

APPENDIX D VIRGIN ISLANDS TREE BOA MITIGATION PLAN — GREAT ST. JAMES ISLAND ACCESS DOCK CONSTRUCTION Introduction Little St. James island habitat for the Virgin Islands Tree Boa, Epicrates monensis granti and two tree boas were seen in 2006 on the island. The tree boa was listed as Federally Endangered in 1979 and the Virgin Islands Endangered and Indigenous Species Act also protects this species. The tree boa is nocturnal and arboreal, the snake forages at night and seeks shelter during the day. The snakes seek refuge in termite nests, debris piles and under rocks during the day. While the snakes' habitat is listed as dry forests, coastal scrub, moist woodlands, mangroves and rocky cliffs, the snakes can occur in any habitat that allows for off ground movement. The structure of the habitat is more important than the species composition; the dock access had some structure which might be adequate for these species. There is an abundant prey base of lizards on the cay, and there is refugia present; logs and rock piles. Fish and Wildlife states that the snakes are extremely difficult to locate even for an experienced snake biologist, and therefore it must be assumed that the endangered species is present, especially when suitable habitat and refugia are present. Tree boas are known to be present the applicant will make every effort not to take (harass, harm, pursue, shoot, wound, kill, trap, capture, or to attempt to engage in such conduct) any of these endangered species. The dock access way will be cleared by hand and rock piles will be dismantle by hand. All personnel involved in site clearing and site construction will be informed of the potential presence of the snake, and the importance of protecting the snakes. Photographs of the tree boas will be shown to all workers as well as a description of their behavior and habitat. All workers must acknowledge that they understand the importance of protecting this rare and endangered species. The site will be cleared directionally from the existing access way towards the shoreline. If tree boas are encountered, work will be stopped in the area of the snake, and the Division of Fish and Wildlife will be contacted immediately. Ever means necessary will be implemented to prevent harm to the tree boa. The DFW will be notified of any snakes observed or capture. Phone numbers for Fish and Wildlife will be posted at the site to aid in immediate notification. EFTA00802834
APPENDIX E Pearson Sustainable Solutions ARTIFICIAL REEFS "When Marine Ecosystems were first being developed, it was just another artificial reef. However, over time they quickly expanded to areas that entail: wave attenuation, snorkeling reefs, oyster reef restoration, mitigation, shoreline stabilization, personal dock reef, coral reef restoration and to be used as a research tool. Our EcoSystems are a culmination of 22 years worth of work in designing and deploying over 35,000 artificial reefs. Its complex (rugosity) design allows small marine animals to seek shelter and protection from larger predators and is ideal for defusing wave energy above the water line. This allows you to place an ecosystems in a high-wave energy area without worry about a storm event damage. The Florida Limestone rock used replicates natural reef substrate and PH. The EcoSystems create an environment for all marine life to attach and this does include boring animals which was something no other artificial reef out there has been able to do. The pile mounted design, utilizing a Pearson Piling mount system, guarantees the unit will stay upright and not sink into the bottom as well as provide proper flushing and creature mobilization."
